Universal Color Chart for the Color Blind

RGB Color Chart with Hexadecimal Codes

What color do YOU mean by “Blue”?

When someone tells you they want something to be red, blue, green or any other color there is a problem. Whether one is color blind or not, your thinking of a green color may be a world away from another person’s thinking of a green color. Using a chart, such as below, an exact color can be chosen by one person, the HEX RGB Code given to another person and, suddenly, each knows EXACTLY what color they are discussing!

More Detail About Colors On Computers

Computer monitors display color in what is called aN RGB format. This means a mixture of the colors Red, Green, and Blue are used to produce any given color. On computers this is expressed in a six-digit hexadecimal (16 based numbers – as opposed to our decimal system which is 10 based numbers) number. The first 2 hexadecimal characters represent the RED component, the next two the GREEN component, and the final two the BLUE component. Since hexadecimal numbers run from 0 to F, where “F” has a value of 16 (as opposed to decimal numbers that run from 0 to 9), a two-digit hex number can represent anything from 0 to 255 (16 x 16 = 256 possible numbers). With the 3 sets of two-place hex codes there are (256 x 256 x 256) 16,777,216 possible color combinations ranging from black (000000) to white (FFFFFF).
